Explanation:
13. 8,448 = 8,450 (round up, 8 more than 5)
14. 89.32 = 89.3 (round down, 2 less than 5, 0 is not needed)
15. 0.05678 = 0.0568 (round up, 8 more than 5, 0 in front are not significant)

Answer:
If a neutral atom has 22 protons inside its nucleus, it will have 22 electrons orbiting the nucleus.
Explanation:
An atom is the smallest amount of matter that undergoes chemical changes and is made up mainly of subatomic particles: electrons, protons and neutrons. The atomic nucleus is made up of protons, with a positive electric charge, and neutrons, which have no charge, while electrons, with a negative electric charge, revolve around the nucleus.
A neutral atom is one that lacks an electrical charge due to a trade-off between the number of its protons and electrons. In other words, although it has an electric charge, it is balanced between protons, electrons and neutrons. So in a neutral atom, the number of electrons equals the number of protons because the negative charge of the electrons is offset by the positive charge of the protons.
